Claims

[Scope of utility model registration request]

A cooling water circulation path is formed between the engine and the radiator, and a cooling water pump is installed in the supply path from the radiator to the engine in the circulation path, and a thermal valve is installed in the return path from the engine to the radiator. In an engine cooling water circulation system provided with a bypass path connected from a valve to an upstream side of the cooling water pump in the supply path, there is a drive other than the engine between the connection part of the bypass path in the supply path and the cooling water pump. A second cooling water pump driven by the engine is provided in the return path between the engine and the thermal valve, and detects the temperature of the cooling water in the return path and transmits a detection signal to the second cooling water pump. An engine cooling device characterized by being equipped with a temperature detector.
